A router is a device that connects one network to another, passing traffic between the two as needed. Enterprise networks can have dozens of routers, and the Internet has thousands. When a user accesses a Web site on the Internet, the traffic might pass through 20 or more routers on its way from the source to the destination. Each one of the routers along the way is referred to as a hop. When a router malfunctions, the computers on each side are isolated from each other. Depending on the design of the networks, the effect of a router failure can be minimal or catastrophic. If the router that connects an enterprise network to the Internet should fail, internal systems are cut off from Internet resources. For a user in the enterprise, this can mean an annoying delay in accessing a Web site, but for a company, this can also mean that customers on the Internet are unable to place orders, which makes it a much more critical failing.

In this practice, you load a DDL trigger example that Microsoft provides for the AdventureWorks sample database. The syntax for this example is correct, but it might not run because the trigger is already present in the database. If you want to take this practice further, debug this problem and create the trigger. If you carry out this practice directly after Practice 1, the first three steps are not required. 1. Log in to your domain at your member server by using either a domain administrator account or an account that has been added to the sysadmin server role. If you are using virtual machine software, log in to your domain and connect to your member server. 2. From the All Programs (or Programs) menu, choose Microsoft SQL Server 2005, and then choose SQL Server Management Studio. 3. In the Connect To Server dialog box, specify Database Engine as the server type. Specify the name of your member server as the server name. Specify Windows Authentication. On the Options tab, specify the AdventureWorks Database and the TCP/IP protocol. Click Connect. 4. In Object Explorer, expand Databases, expand AdventureWorks, expand the Programmability folder, and expand Database Triggers as shown in Figure 9-13. 5. Right-click ddlDatabaseTriggerLog and choose Script Database Trigger As. Figure 9-14 shows this selection.
